First of all, I'm not convinced liquid oxygen is real because, if it is, why can't I breath underwater? I want a merman, damnit. But if it is real, this is a video of Theo Gray lighting a charcoal grill with the stuff. Apparently it's dangerous, but I find it hard to believe. I mean, it's just a liquid. Jesus, it's not like I just ate and wanna go swimming in the stuff.
